What is human mobility?

The geographic displacement of human beings in space and time, seen as individuals or groups. Barbosa et al., 2018

missing

Individual movements.

missing

Population trips.

How is human mobility supported by transport systems?

Through a variety of transport modes, e.g.,




ride-sourcing public transit private car


- Transport modal disparities
Different modes present distinct characteristics such as travel time and spatiotemporal distribution of trips.

Background

  • Transportation presents a major challenge to curbing climate change.

  • Better informed policymaking requires up-to-date empirical data with good quality, low cost, and easy access.

  • Emerging data sources enable deep and new insights from large-scale collection of human movement and transport systems.

Research questions and present work

  1. What are the potentials and limitations of using emerging data sources for modelling mobility?

  2. How can new data sources be properly modelled for characterising transport modal disparities?
